calculate the work done by a person pulling a 50kg sled, at constant velocity, along the snow at an angle of 50 degrees from vertical for 5m. the coefficient of kinetic friction between teh sled and the snow is 0.50. Please include a free body diagram.
A box is put on a slide to move it from one part of a factory to another the slide is at an angle of 20 degrees below the horizontal the coefficient of friction between the box and slide is 0.352 what is the acceleration of the box.
A 23.00 kg chair initially at rest on a horizontal floor requires a 364N horizontal force to set it in motion. Once the chair is in motion, a 328N horizontal force keeps it moving at a constant velocity. A 23.00 kg chair initially at rest on a horizo..
